Based on the analysis of the data obtained as a result of calculations of the mathematical model, a method of determining the optimal sequence of capture (destruction) of enemy objects, in which the percentage of losses is minimal (at a fixed value of initial combat potential) or the required initial potential (for a given percentage of losses) is the smallest.

The timeliness of the issuance of information on enemy air attack means to anti-aircraft missile divisions is crucial for their reliable defeat. Uncertainty of air attack means, namely the height of their use and directions of attack on troops and objects, necessitates the need to consider several options for building the spatial structure of the enemy's reconnaissance system in order to optimize it.</p> <p>The article proposes a method for determining the rational spatial structure of the enemy reconnaissance system, in which the optimization criterion is the effectiveness of the enemy reconnaissance system, which is estimated by the mathematical expectation of the relative number of air attack means from the strike, detected and timely information divisions.</p> <p>The effectiveness of the enemy's reconnaissance system is defined as the product of the probability of identifying the objectives of the enemy's reconnaissance system and the probability of timely issuance of information on them to anti-aircraft missile divisions. The probability of detecting the target of the enemy air reconnaissance system is determined taking into account the overlap of the radar field, the probability of timely delivery of information to anti-aircraft missile divisions using the normal Laplace distribution function. When assessing the effectiveness of the enemy air reconnaissance system, the possible ranges of heights of the use of air attack means and the directions of their strikes on troops and objects are taken into account. The distribution of air attack means by altitude ranges is carried out by the heuristic method. Coefficients of importance (danger) of directions of blows of means of air attack are defined with use of an expert method of ranking.</p> <p>Variants of the spatial structure of the enemy reconnaissance system differ in the location of radar stations on the ground. A variant of the spatial structure is considered rational, which corresponds to the maximum efficiency of the enemy's reconnaissance system.</p> <p>The procedure for using the developed method of determining the rational spatial structure of the enemy air reconnaissance system is shown by example. The technique can be used during the organization of reconnaissance of the enemy air by the control bodies of radio troops.</p> Oleksii Zahorka , Serhii Polishchuk , Iryna Zahorka Copyright (c) 2021 Олексій Загорка, Сергій Поліщук, Ірина Загорка http://sit.nuou.org.ua/article/view/223483 Fri, 28 May 2021 00:00:00 +0000 MODEL AND METHOD OF INFORMATION FLOW MANAGEMENT IN THE TELECOMMUNICATIONS NETWORK OF THE TACTICAL LEVEL OF COMMAND http://sit.nuou.org.ua/article/view/217707 <p>This article provides a review and analysis of trends in the development and application of the latest technologies and means of communication in the units of the tactical level of command of the Armed Forces of Ukraine.

The use of an unmanned aerial vehicle in the conditions of requirements and restrictions, the flight technical capabilities of an unmanned aerial vehicle, the availability of means of destruction of the enemy suggests a large variety of flight route options, which makes it difficult to make an informed decision on building the optimal flight route for an unmanned aerial vehicle. As the experience of the practical application of submarines shows, the conditions, requirements, restrictions imposed on reconnaissance tasks, the influence of external factors, the account of the most important objects for overflight, can contradict each other, creating uncertainty when giving priority to any of them in planning. The developed method of formalizing knowledge about the process of flight planning of an unmanned aerial vehicle based on INMT2 allows one to formalize factors that take into account the tactical conditions for conducting aerial reconnaissance, the influence of the external environment on the flight range of an unmanned aerial vehicle in the form of linguistic and interval-estimated parameters for each option, which allow taking into account uncertainty; to form the domain of definition of linguistic variables used to describe the tactical conditions for conducting aerial reconnaissance and the influence of the external environment on the flight range of an unmanned aerial vehicle; to form the most significant ground objects from the set of the most important objects of aerial reconnaissance on the basis of an assessment of the degree of non-dominance of elements; to formalize the flight strategies of an unmanned aerial vehicle for each possible variant of operational construction, the influence of the external environment in the form of fuzzy production rules, where fuzzy linguistic expressions are used as an antecedent, consequent.</em></p> Oleksandr Permiakov, Natalia Korolyuk, Anastasiia Korolyuk, Liudmyla Korotchenko Copyright (c) 2021 Олександр Пермяков, Наталія Королюк, Анастасія Королюк, Людмила Коротченко http://sit.nuou.org.ua/article/view/231269 Wed, 09 Jun 2021 00:00:00 +0000 THE METHOD OF A JOINT AVIATION GROUP FORMING http://sit.nuou.org.ua/article/view/228968 <p><em>Today, more information appears about joint flights of manned and unmanned aviation to perform a common task.
